Today effectively marks the end of the primary election season and the true beginning of the general elections. It’s not only one of the last primary days but one of the biggest, including Delaware, District of Columbia, Maryland, New Hampshire, New York, Rhode Island and Wisconsin. [Ed. note: Jon will be liveblogging results all night. Delaware polls close at 8pm EDT, with a number of others closing at 9. Look for results and reaction at FDL's Elections page.]
